能源消耗中,电能占有很大的比重,而风机和水泵的用电量又占工业总用电的一半左右,这其中一部分电能是由于设备效率低,调节流量方法不当而白白消耗掉了,没有发挥应有效益。近年来北京市一些企业在有关单位支持下,上了一些电机变速的项目,取得一些成果,但目前尚缺少面上的总体情况资料。为此,北京市节约能源办公室组织有关单位成立电机变速节能调研组,对所属若干企业节电情况作了调查,初步摸清了一些情况,下面将这些情况作一综合
In energy consumption, electric energy occupies a large proportion, and the electricity consumption of fans and pumps accounts for about half of the total electricity consumption in the industry. This part of the electricity is consumed because of the low efficiency of the equipment and improper adjustment of the flow rate. Play its due benefits. In recent years, with the support of the relevant units, some enterprises in Beijing have made some motor speed changes and achieved some results, but at the moment there is no general information on the surface. To this end, the Beijing Office of Energy Conservation organized the relevant units to establish a research group for motor speed change and energy conservation, and investigated the energy saving situation of some of its subsidiaries, and made preliminary investigations into some situations.
